I got an error in the elastic search indexer module.i have installed elasticsearch version 7.9 with magento2.
{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Unknown filter type [phonetic] for [phonetic]"}],"type":"illegal_argument_exception","reason":"Unknown filter type [phonetic] for [phonetic]"},"status":400}
how can i fix this issue ??
Looks like an issue with the elasticsearch configuration, the plugin is required, try this out!
sudo /usr/share/elasticsearch/bin/elasticsearch-plugin install analysis-phonetic
sudo service elasticsearch restart
Then try reindexing again.
